طلبات التشييد والبناء / سويسرا

we want to provide ourselves with prefabricated materials, in order to build houses, buildings and even hotels. Are you approved for Swiss standards? Can you get a U value close to 0.1? We have several constructions to do, and wish to work with you as soon as possible. Do you provide the floors, kitchen, bathroom, shower, window, blind? Or do you have a partner who could supply them to us at the same time?
